FAQs
Will this fit my standard (non-M Sport) G30 5 Series?
No, this extension is designed exclusively for M Sport variants. Standard models have a different bumper profile and factory diffuser setup.
Do I need the factory BMW diffuser for this to work?
Yes, this bumper extension is engineered to work with the factory M Sport diffuser only. It will not fit without one.
Is professional installation necessary?
Whilst mechanically straightforward, professional fitting ensures correct alignment and finish. We recommend professional installation available in Southend-on-Sea — contact Project Styling for details.
Is the gloss finish easy to keep clean?
The UV-protected gloss finish is designed to be durable and maintain its shine. Standard car care (gentle washing and occasional detailing) keeps it looking fresh.
